To f//ZL whom it may concern:

Be it known that I, DANIEL M. VINANS, a citizen of the United States of America, residing at Binghamtomin the county of Broome and State of New York, have invented a ce'rtain new and useful Improvement in Firearms7 of which the following is a description, reference being had to the accompanying drawings, where- Figure l is a view of the middle portion of a (closed) double-barreled breech-loadin g gun embodying said invention with a part thereof in central vertical longitudinal section. It is chiefly the purpose of this view to show the extractorpin and the cam or tappet which operates it when the gun is being opened. Fig. 2 is a view from the rear of the parts which are shown in Fig. l, the gun in this view being opened. Fig. 3 is a view of the under sideof a portion of the barrels, exposing the extractor-stems to view. Fig. 4 is a view of the under side of parts of the gun with the forefend piece removed, bringing the ejector-springs into view. Fig. 5 is a View of parts of the closed gun in central vertical longitudinal section, bringing into view the rotarily acting hammer and the connection therefrom to the ejector-spring. Fig. Gis a view of the `same parts which are shown in Fig. 5 with the gun opened.

The object and purpose of the improvement are to provide breech-loading gunsdouble-barreled Shotguns, for instancewith a novel feature of cartridge-shell ejection additional to the ordinary positive-extraction feature of the prior art, that additional feature being operative only after the hammer has been snapped or let down. One practical result of mechanisms of this general class is that in opening a double-barreled breech-loading shotgun only that shell is thrown out which has been fired or exploded.

In the accompanying drawings the letter a denotes the frame.

The letters b denote the two barrels, situated side by side in the ordinary manner.

The letter c denotes the pivot-pin, which pivotally attaches the frame to the barrels.

The opening and closing movements of the gun are like those of the prior art. The opening of the gun cocks the hammer and ejects the shells. Each barrel has a separate extractor d, carried by an extractor-stein e, adapted to have a limited longitudinal reciprocation in dovetailed grooved ways formed in the metal underneath the barrel-bore. In opening the gun both the separate extractors d are moved rearwardly a certain distance with a positive niption by the extractor-pinf striking against the extractor tappet or cam g, the tappet g being stationary in its relation to the frame. Then when the gun is opened the pin f is necessarily moved rearwardly in its relation to the barrels. as it moves along the surface of the tappet, and as a consequence it pushes the extractors rearwardly in their relation to the barrels at the same time. This is a positive movement and always takes place when the gun is opened. In closing the gun the shoulder 7L on the lockframe strikes the extractors and forces them both (and with them the extractor-pin) back to the forward limit of their longitudinal play, which is their normal position in a condition of rest This operation of two extractors by a single extractor pin and tappet is believed to be a new feature iii firearms.

The additional feature of shell-ejection will nowbe described. That operation of the extractors already described always takes place when the gun is opened. It starts both the shells back from their seats in the shell-chambers and leaves them lying so loosely that one can readily grasp them with the iingers. The gun has, as to each barrel, an additional degree and feature of shell-ejection only operative as to either barrel when its hammer has been snapped or let down that is, generally and practically, only after the barrel is fired.

As has been mentioned, each extractor d is borne yby and carried on an extractor-stem e. The front end of the extractor-stem is equipped with a cam-surface e', called herein a cam.

The letter t' denotes a hammer (there being one for each barrel) having a rotary movement both in cocking and liring.

The letter It denotes a pawl pivotally attached to the hammer, with its front end'taking into a socket in the rear end of the piston Z.

The letter m denotes a spiral spring bearing rearwardly on this piston. It is this ICO - ersing the slot r.

tise formed in the forward end of the lockframe. A spring u, acting through an intermediate pin o, pushes the ejector-spring to the rearward limit of its play when permit ted, at which times the tenon s enters the mortise t. rIhe rear end of the upperleaf of the ejector-spring is equipped with the camsurface o', called herein a cam.

The cooking movement of the hammer is synchronous with the opening of the gun, a matter of the prior art not necessary here to be described. In such an opening and cocking movement the extractor d moves positively, asvr already described, a certain djistance, 'and the extractor-stem c moves. with it..

Meanwhile (supposing the hammer ,to have been in thesnapped position at the opening movement of the gun) the ejector-spring o is compressed, its. under leaf being pressed toward its upper leaf through the coperating action of the tenon rand lnortiset. X'Vhen in the rearward movement` of the extractorstem til@ 'WTO cams e and o overlap each other,

th@ act-ion of; the now-compressed ejectorspring is brought into play, the force thereof being exercised to press, these two oblique surfaces against each other, with the result that the, extractor-stein with the extractor which it carries is forced rearward with a sudden kickingv motion beyond and additional to the positive extracting movement already described, giving the extractora force and movement adapted to throw theA exploded shell enti-rely out ofthe gun. Now in opening the, gun (whichcocks the hammer) the rodi n forces the ejector-spring o tothe limit of its forward movement and hold-s it there,`

no. matter how often the gun is opened andv closed, ujntil the hammer is snapped, the, ejector-spring in this locked position having no. cooperative action with the extractorstem. Whenthe hammer issnapped, the rodn retracted and the ejector-spring, then unlocked, moves rearward under the influi ence of spring u to, coperate,v as before, with the extractor-stem when the gun is opened.

I claim as my improvementl. In a breech-loading firearm, the combination of the two barrels, the separate extractors for the two barrels, the' single extractor-pin adapted to coperate with both extractors, and means adapted to operate the extractor-pin in the opening movement of the arm, and a cam projection on the forward end of the extractor-stem, an ejector-spring, and a cam-surface on the end of the said spring acting upon the cam-surface of the extractorstem to eject the extracted shell, all substantially as described and for the purposes set forth.

2. In a breech-loading firearm, the combination of a gun-frame, a barrel pivotally attached to said frame, a hammer for exploding the cartridge, the extractor borne on the reciprocatory extractor-stem, a cam-surface on the forward end of the said extractor-stem, the ej ector-sprin g having an inclined camsurface acting on the said cam-surface on the forward end of the extractor-stem to eject the vrextracted shell, and means intermediate of i said spring and hammer adapted to hold said spring from operation while the hammer is f cocked, all substantially as described and for the purposes set forth 3,. In a breech-loading firearm, the combination of a gun-frame, a barrel pivotall'y attached to said frame, a hammer for exploding i the cartridge, the extractor, means for giving' i the extractor positive extracting movement y in the opening of the arm, the reciprocatory extractor-stem. provided with a cam, the pawl pivotally att-ached to the hammer, the piston adapted to be actuated by said pawl, the hammer-sprin g, the ej ector-spriI-i g and the rod extending from said piston and adaptedto operate on said ej ector-sprin g, all substantially as described and for theI purposes set forth.' 4;. In a breech-loading firearm, the combination of a gun-frame, a barrel pivotally attached to said frame, a hammer for exploding the cartridge, the extractor, means adapted r for giving the extractor positive extracting movement in the opening of the arm, the reciprocatory extractor-stem provided with its cam, the mortise t the reciprocatory twoleaved ejector-spring provided with its cam and with its tenon taking into the, mortiset t,

the pawl pivotally attached to the hammer, the piston adapted to be actuated by said4 pawhthe h ammer-sprin g,and the rod extending from said piston and adaptedv to operate onsaid ejector-spring, all substantially asdescribed and for the purposes set forth.`
